Vibration damper for building

Abstract

The invention relates to a vibration damper for a building. The vibration damper comprises a connecting rod assembly, a cylinder barrel assembly and a base joint, wherein the connecting rod assembly comprises a connecting rod, a guider sub-assembly and a piston sub-assembly; the guider sub-assembly mainly comprises an oil seal gasket, an oil seal and a guider; the connecting rod is arranged in an inner cavity of the upper section of a cylinder barrel through the centers of the oil seal gasket, the oil seal and the guider and can slide and rotate in inner holes of the oil seal and the guider; the upper end of the connecting rod stretches out of the cylinder barrel and is fixedly connected with a connecting rod joint; the piston sub-assembly which is provided with a circulating valve and a restoring valve is fixedly connected to the lower end of the connecting rod; the cylinder barrel assembly comprises a valve seat sub-assembly and a floating piston which are positioned below the piston sub-assembly; the valve seat sub-assembly is provided with a compensating valve and a compression valve; liquid working oil is filled in a steel cylinder between the floating piston and the guider; and gas with certain pressure is filled in a sealing gas chamber below the floating piston. The vibration damper has a compact structure, and can produce high damping force at a low movement speed to quickly attenuate vibration and absorb noise and high-frequency vibration.

Description

【Technical field】 [0001] The invention relates to a vibration damping device for a house, in particular to a vibration damper suitable for a wooden structure house. 【Background technique】 [0002] In earthquake-prone countries and regions, the earthquake resistance of houses is extremely important. At present, there is no domestic manufacturer producing shock absorbers for houses. In foreign countries, house shock absorbers are still in the development and design stage, and it is extremely necessary to develop a new type of shock absorber with excellent performance. House shock absorbers to meet the needs of the market and solve the earthquake-proof problems of wooden houses in earthquake-prone countries and regions. 【Content of invention】 [0003] The technical problem to be solved by the present invention is to provide a novel house shock absorber with compact structure and excellent performance, so as to solve the earthquake-proof problem of wooden houses in countries a...
